Benefits of technology

The impact load carrying means at either one or both of upper and lower end portions desirably overlaps a rigid stationary portion forming side part of a vehicle body. The double door construction thus constructed cooperates with a side body of the vehicle thereby to provide improved side body strength against lateral impact upon an occurrence of a lateral collision of the vehicle.

Problems solved by technology

In addition, the motor vehicle having no center pillars is hard to ensure mounting rigidity of a functional member such as a seatbelt retractor.

Embodiment Construction

In the following description, the term "outer side" as used herein shall mean and refer to the side on the exterior of the vehicle body and the term "inner side" as used herein shall mean and refer to the side on the interior of the vehicle body.

Referring to the drawings in detail, and, more particularly, to FIG. 1 showing part of a vehicle body 1, the vehicle body 1 is equipped with an outward opening type of double doors, namely front and rear doors 2 and 3, according to an embodiment of the present invention. A similar pair of doors (not shown) are provided on the opposite side of the vehicle body 1. The front door 2 at a front end is pivotally mounted to the vehicle body 1 by hinges (not shown). The rear door 3 at a rear end is pivotally mounted to the vehicle body 1 by hinges (not shown). These front and rear doors 2 and 3 open outward in opposite directions to provide a single uninterrupted opening, i.e. a doorway through which front and rear seats are accessed, in a side body...

Abstract

A double door structure which has front and rear doors opening outward to form an uninterrupted opening to front and rear seats has an impact load carrying assembly for forming a side body reinforcing structure for protecting passengers against a side collision. The impact load carrying assembly includes an impact bar extending to and overlapping a side sill of a vehicle body, an upper bracket fixedly mounted to the impact bar and located to overlap a roof side rail of the vehicle body and a lower bracket fixedly mounted to the impact bar. The upper bracket mounts a latch and a belt anchor of a seatbelt system thereon and the lower bracket mounts catch pins forming part of a door catch mechanism operative to prevent movement of the door upon an occurrence of a side collision.

Description

1. Field of the InventionThe present invention relates to a door construction for a vehicle provided with double doors that open outward to form a single uninterrupted doorway to front and rear seats which ensures strength of a side body against lateral external impact even though having no center pillars.2. Description of Related ArtMotor vehicles with double doors, typically such as front and rear doors opening outward, provide a single doorway to front and rear seats when the double doors open. Such a motor vehicle has no center pillars and, in consequence, has need to be equipped with improved rigidity of a doorway structure and strength and rigidity of door units. As described in, for example, Japanese Unexamined Patent Publication No. 10-250370, one of general measures for improving strength and rigidity of a door unit is to provide the door unit with an impact load carrying bar extending in a lengthwise direction in an inside space of the door unit so as thereby to ensure str...
